About IDInfo for Firefox

What is Firefox add-on?

IDInfo for Firefox is live on Mozilla Add-ons (AMO) (v1.1.0, published May 2026). Add a small button to your toolbar — on any supported social profile, click it and a new tab opens on idinfo.ws/<platform>/<username> where the site resolves the permanent numeric ID.

Built on the WebExtension API (Manifest V3), signed by Mozilla, and installable in one click from the official Firefox add-ons store. Extension ID: idinfo@idinfo.ws.

FAQ

Firefox add-on — common questions

Where do I install IDInfo for Firefox?

From the official Mozilla listing: addons.mozilla.org — IDInfo Social Profile ID Lookup. One click installs the signed add-on.

Will it work on Firefox for Android?

Firefox for Android supports a curated subset of WebExtensions. Install from the same AMO listing when your device supports the add-on.

What data does the extension collect?

None. The extension only reads the URL of the active tab when you click its icon, then opens the matching idinfo.ws profile page. No analytics, no telemetry — AMO lists zero data collection.

Can I use IDInfo without the add-on?

Yes — paste any profile URL on the home page or visit idinfo.ws/<platform>/<username> directly.
